When boiled, meat loses 45%. How much boiled meat will be obtained from 15 kg of fresh meat?

Method 1.

We find the mass that the meat will lose during cooking.

To do this, multiply its initial weight by the specified number of percent.

We get:

15 * 45% = 15 * 0.45 = 6.75 kg.

Thus, after cooking, there will be:

15 – 6.75 = 8.25 kg of meat.

Method 2.

We designate all fresh meat as 100%.

Since during cooking it loses 45% of its weight, it means that it will remain:

100% – 45% = 55% of the initial weight.

Thus, we get:

15 * 55% = 15 * 0.55 = 8.25 kg.

Answer:

After cooking, we get 8.25 kg of meat.
